Dynamic scaling near the Kasteleyn transition in spin ice: critical relaxation of monopoles and strings following a field quench (opens in new tab)

arXiv:2603.19408v1 Announce Type: new Abstract: We study dynamics in classical spin ice following a magnetic field quench to close to the Kasteleyn transition, using Monte Carlo simulations and dynamic scaling theory to characterize the relaxation of the magnetization and the density of magnetic monopoles. We have previously argued that this dynamics can be described in terms of seeding and growth of strings of flipped spins, and our results here demonstrate that a solvable stochastic model ...
